So everything is fine with Project M. Until I decided to download the Smash 3C texture pack. I used the included GCT file for the costume expansion, and when I try to launch Project M, it keeps sending me to the Wii Menu, or loading up V brawl. It works perfectly when using the GCT that Project M 3.6 comes with, but when trying to use the one provided for the texture pack, it doesn't work properly. Any tips on what to do?  

I hope this is the right place to ask this. Anyway, here's my problem. Every time I try to open a a folder in the tool, it gives me some "unhandled exception" error or something, and I can't do anything. Is there a way to fix this?
